acer e4w charge usb 検証

More than 1 year has passed since last update.

acer e4w というアクティブシャッター3Dグラスを買ったがどうも充電規格が特殊で平型8ピンUSBの単純な充電用ではないケーブルを使用しているようなので、サンハヤト USB用変換基板 CK-39を購入し検証してみた

結論
3pin D+とGNDをプラスマイナス逆につけると充電されるっぽい

平型8ピンってなに?デジカメとかであるらしいけどピンに部分見てみるとどのメーカーも微妙い違うし仕様がネットじゃみあたらない
海外規格?とりあえず入手性も検証性もめちゃくちゃ悪い規格である。
ボタン電池のやつ買ったほうが無難ですな
